PORTABLE STEAM ORV VAPOR BATH APPARATUS.

SPECIFICATION forming part of Letters Patent No. 670,645, dated March 26, 1901.

Application filed February 23, 1899. Serial No; 7 O6,605- (N0 mode -l To all whom it may concern:

Be it known that LMOSES ROSTOVSKY, a citi- Zen of the United States of America, residing in the city and county of San Francisco, in the State of California, have invented certain new and useful Improvements in Portable Steam or Vapor Bath Apparatus, of which the following is a specification.

My invention relates to an improved construction of portable room' or cabinet for giving steam or vapor baths and a portable generating apparatus for supplying steam or vapor' for the bath.

The cabinet is constructed in parts to readily separate and fold into small compass for stowing away or transporting it from place to place.

The generator has severalnovel points and features of construction that render it capable of being handled andused with safety by unskilled persons. It is self-regulating as to the water-supply, so that the quantity thereof admitted to the generator is controlled by the consumption of the steam, and any excess of production of steam over the quantity drawn from the generator is condensed and returned to the water-space.

The following description explains at length the nature of the said improvements and the manner in which I proceed to construct, apply, and carry out the same, reference being had to the drawings that accompany and form part of this specification.

Figure 1 of the drawings is a longitudinal sectional view of the cabinet set up for use.

Fig. 2represents in elevation the steam-generator mounted on a stove or furnace. Fig.

3 is a vertical transverse section at 00 to, Fig.

1. Fig. 4: shows the parts of the cabinet fo1d-' ed up. Fig. ,5 is a vertical sectional view of the generator on an enlarged scale.

A indicates the floor of the cabinet, and A A are upright end panels attached to the floor by hinges a a B is the top or roof, and B B are side panels attached to the top B by hinges b b One of the sides B is attached to the top B by a strip 19 corresponding in Width to the thickness of the other side piece B, so that the two sides will lie fiat when folded together, as shown in Fig. 4. A door D is provided in one of the side pieces by which to enter the cabinet, and there are to the sides of the opening by hinges h 727 and held normally open by a weighted lever H. These gates are arranged to be held down by the weight of the bat-her or an attendant,

the quantity of steam in the cabinet and the conditions of the atmosphere being affected and controlled by opening or closing these gates.

A steam-valve I on the end of a supply-pipe I K is set in an aperture in one end of the cabinet, from which it is detachable by providing a screw-coupling la on the end of the supplypipe. Any suitable hand-operated steamvalve will answer for this purpose; but I propose to employ one of the self-closing kind, operated by a pull cord or chain, so that the admission of steam can be more easily and quickly controlled. Where the same is required, an opening X can be provided in the top of the cabinet for permitting the head and neck of the bather to project outside the steam-space, in which case aolose joint is socured around the neck to prevent the loss of steam or heat by using a tubular packing X of flexible material, such as silk or cloth.

The generator is constructed with a steamproducing compartment M and a water-feeding tank M, one being mounted on the other and the former having a flat bottom, so that it can very readily be placed on a stove or f ornace.

Water is supplied to the upper vessel M through a pipe 1?, connectible outside with which the valve is held up to its seat by a.

spring and is opened by pressure of a lever R, acting upon the end of the valve-stem. The weight for this purpose is obtained by the water caught and retained in the pan S, which is suspended under the cock, the body of Water accumulating therein being sufficient to hold the cock open when the vessel is empty and until the gradual rise of the water-level in the vessel as the water running from the pan into the vessel increases in quantity beneath the float. An overflow for the water from the pan into the vessel is provided by fixing an upright overflow-tube in the bottom of the pan.

T is a water-tube leading from the bottom of the vessel M perpendicularly downward through the space in the lower vessel M and terminating in a heating-coil T, having an outlet T v This coil is located in the waterspace of the generator below the level of the water therein.

T is a cock in the tube T, operated by a leverT and a float T the Weight of the float being taken ofi the lever and the cock closed by the rise of the water-level.

As thus arranged the flow of water from the upper vessel into the lower one is regulated by the rise and fall of the water-level in the generator. 1

U is the steam-outlet, to which the inletvalve of the cabinet is connected by a pipe K of suitable length.

W is a return-tube connecting the steamspace of the generator freely with the Watersupply tank. Through this tube the steam is turned into the water vessel to effect condensation when the consumption is less than the production, and thereby maintain equal pressure in the generator and tank.

As thus constructed the apparatus provides a simple, eifective, and safe generator for use in connection With a cabinet or closed apartment for giving steam-baths.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a portable vapor-bath apparatus, a cabinet composed of a platform having end panels, the removable top having side panels, the trap beneath the platform, an opening communicating therewith, hinged gates controlling said opening, and the weighted lever as a means of opening the gates.

2. In a portable vapor-bath apparatus, a cabinet composed of a platform having foldable end panels, the removable top having side panels attached by hinges to fold upon the top, the trap beneath the platform, an opening communicating therewith, hinged gates controlling said openi ng,and the weighted lever asa means of opening the gates; the top and side panels having apertures for light and for access to the cabinet.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
